I remember some years ago Tesco started to sell Naan bread, that to me looked like the real deal, it was labelled on the back "Abdul's Southall, they were great, sprinkle with water and microwave for 1 minute and then foil up.
They would always sell quickly, after about a year, no Abdul any more, now Tesco, not quite as good but ok.
So now im sure now what we get from supermarkets is the results of spies watching the BIR's being made and thinking how can we get machines to turn these out.
They are certainly giving it a go.
